1956 Doubled Die Reverse DDR-010

Description

Exhibiting a dual-intensity spread pattern across three reverse inscription areas, DDR-010 on the 1956 Proof Jefferson Nickel presents medium spread on AMERICA alongside light spread on STATES OF and CENTS. Die markers UVC-927 and DMR-014 confirm this working die. The variation in doubling strength — medium on AMERICA but light on the flanking text areas — indicates the hub displacement vector produced its peak visible effect at AMERICA's position on the die, with diminishing offset as the distance or angle from the primary misalignment axis increased toward STATES OF and CENTS. This triple-area distribution across different intensity levels provides a rich diagnostic framework: collectors can confirm the variety by verifying that AMERICA shows the most pronounced doubling while the adjacent inscriptions carry proportionally subtler displacement. As a proof coin struck at the Philadelphia Mint, this nickel was produced on polished planchets with mirror-finish dies, and the reflective proof surfaces amplify the visibility of both the medium and light spread against the mirrored fields. The 1956 proof nickel was available exclusively through annual proof sets in standard copper-nickel composition. DDR-010's catalog position reflects extensive documentation of 1956 proof reverse varieties, with at least ten distinct doubled die reverses identified from this production run.
